Robinson: The ‘ambush’ Ross didn’t see coming

That's four coaches banished by their football clubs and we haven't even reached the end of Round 23.

Brendon Bolton. Brad Scott. Alan Richardson. And now Ross Lyon.

As Lyon said, footy's a brutal business.

Lyon's sacking at Fremantle was, we learnt, months in the planning and three days in the execution.

The loss to Essendon on Saturday night prompted an impromptu board meeting, where it was decided, because the Dockers wouldn't play finals this year and Lyon would not coach out his contract in 2020, then why keep him.
